Application filed. September 18, 1922. Serial No. 588,836.

To all whom it may concern.

Be it known that I, Orro A. LANoos, a citizen of the United States, and a resident of Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Curling Irons, of which the following is a specification.

My invention relates to curling irons and particularly to that type in which the heating rod is provided with a detachable hair clamping jaw so that the rod may be used alone or with the clamping jaw for different styles of hairdressing.

The object of the invention is to provide a more practical and more simple separable hinge connection between the heating rod and the clamping jaw so that the jaw can be readily applied or removed. The object is also to have the construction and arrangement such that the cost of manufacture can be materially reduced.

The various features of my invention are embodied in the structure shown on the ac companying drawing, in which Fig. 1 is a side elevational view of a curling iron,

Fig. 2 is a side elevational view partly in vertical diametral section and with the clamping jaw raised,

Fig. 3 is a sectional view on plane 3-3, Fig. 1,

Fig. 4: is a sectional view on plane 4-4, Fig. l, and

Fig. 5 is a sectional view similar to Fig. 4 showing a modified arrangement.

The heating rod 10 of the iron shown is inserted in the handle 11, a ferrule 12 being secured around the neck 13 of the handle. The rod may be solid to be heated over a flame, or it may be hollow to receive an electric heating element (not shown) to which current is supplied by conductors 14 in the well known manner. The clamping jaw comprises the body part 15 of semi-circular cross section and the tail piece 15 extending at an angle therefrom, the jaw being formed integral out of sheet metal. At the base of the body part the opposite sides 16 and 17 are deflected inwardly to form hinge projections 18 and 19, these hinge projections being a distance above the top of the heating rod 10 when the clamping jaw is closed. Surrounding the rod inwardly of thehinge projections is'a hinge fitting comprising the annular body part 20 encircling the heating .its pocket by a rivet 28, this rivet rod, and the flange part 21 bent to hook form to receive at its ends the hinge projections 18 and 19 t0 thus hinge the clamping jaw t0 the heating rod. The preferably formed of sheet metal and the inner section 22 of the body part 20 is turned rearwardly and seamed to the radial flange 23 at the outer end of the ferrule 12, the fitting being thus rigidly secured to the ferrule. The hook flange 21 extends transversely across the topof the heating rod with its ends a sufficient distance away from the rod to leave the space 24 through which the h nge pro ections may pass to or from their hinge positions in the ends of the hook flange. I

Atits end the tail part 15- of the'clamping aw is deflected downwardly to form a rec'- tangular pocket 25 for the upper end of a spring 26 whose curved lower end 27 bears on the ferrule 12. The spring is secured in also supporting a finger plate 29 preferably of heat insulating material such as wood or fibre. The spring tends to hold the hinge projections up in the ends of the hook flange, and the clamping jaw body 15 a ainst the heatmg rod as shown in Fig. 1. ressure on the plate 29 will cause the clamping jaw to swing with its body 15 away from the heat-- mg rod so that the rod can be inserted underneath the hair to be curled or waved. The spring will tend to keep the clamping jaw in hinged connection with the heating rod but by exerting downward and forward pressure on the tail part 15' the hinge pro-- ectlons can be readily disconnected from the hook flange and the clamping jaw removed, downward pressure bringing the hinge projections into alignment with the space 24 and forward pressure carrying the projections through this space. To re-apply the clamp-- hinge fitting is ing jaw it is placed on the heating rod in.

permit of passage therethroughv b the pin during removal-or application of t e clamp-- 'ing aw.

The locationing of the hinge projections or in to be above the top of the heating rod wi permit comparatively wide separation between the jaw and red at the base of the .jaw, and when the jaw is closing thehair will not be shifted forwardly on the rod but will retain its uniform distribution.

' applied.

I do not desire to be limited to the exact construction and arrangement'shown and described as modifications are possible which will still come within the scope of the appended claims,

I claim as follows:

1. In a curling iron, the combination of a heating rod, aclamping. jaw, a hinge hook extendin transversely and above the heating rod at t e inner end thereof, cooperating hinge structure on said clamping jaw detachably received by said hinge hook, and a spring for yieldably holding said hinge hook and structure in hinged relationship and for resisting swing of said clamping-jaw;

2. In a curling iron, the combination of a heating rod, a clamping jaw, a hinge hook extending transversely and above the heating rod at the inner end thereof, hinge projections on said jaw having detachable engagement in said hinge hook whereb said jaw may be swung, and a spring yie dably holding said hinge projections in said hook and. resisting swing of said jaw.

3. In a curling iron, the combination of a heating rod, a clamping jaw, a hinge hook extending transversely above said heating rod at the inner end thereof, hinge projections' on said jaw engaged'by said hinge hook to hinge the jaw to said rod, and a spring yieldably holding said projections in said hook and resisting swing of said jaw, there being space below the hinge hook for the passage of said projections into or out of en agement with said hook.

4. n a curling iron, the combination of a cylindrical heating rod, a clamping jaw of semi-circular cross section for said rod, a-

hinge hook extending transversely of said rod at the inner end thereof, hinge projections deflected inwardly from the opposite walls of said jaw at the inner end thereof, there being space between said hinge hook and rod for permitting said projections to be inserted in the ends of said hook or to be withdraw-n therefrom, and a spring for yieldably holding said projections and hook the combination of a heating rod, a clamping jaw for said rod, a hinge fitting encircling said rod at the inner end thereof and having a hinge hook flange extending across said rod, hinge pin structure at the inner end ofsaid jaw for engaging with said hook fiangeto hinge said jaw to said rod, and a sprin for holding said hinge pin structure an hook in hinged connection and for resisting swing of said jaw.

6. In a curling iron of the class described, the combination of a heating rod, a handle therefor, a ferrule secured to said handle and said rod, a hinge hook secured to said ferrule and extending transversely over the rod, a clamping jaw having projections for engaging with said hook to hinge the jaw with reference to the rod, and a spring for resisting swing of .said jaw.
